8. Maximum Capacity (cont'd):
c. Watch the amount of grain on the window
in the receiver tank. Keep the window full
yet keep the product moving.
There are several ways to control the
amount of grain on the window:
i. Decrease the amount of grain entering
the nozzle.
ii. Increase airflow by opening air-slide.
The airlock acts as a seal between the
vacuum and pressure sides of the circuit.
Increasing the airlock speed normally will
remove product from the receiver faster.
Refer to Airlock Speed Chart as a guide.
When moving certain specialty crops, ie,
sunflower seeds, lentils and others, it is
necessary to slow the airlock speed to allow
more time for the product to enter the pocket.
Experiment with slowing the speed to
increase the capacity.
Airlock speed can be run too fast, not
allowing the product to fill each airlock
pocket. Never exceed the recommended
speeds!
9. Specialty Crops:
a. Operating:
When handling specialty products such
as sunflower seeds, lentils etc, it is
recommended that the PTO speed be
reduced by 1/4 to 1/2 the rated RPM.
This gives a gentler action through the
machine.
